I don't think it's fair to cancel Groundhog Day, as Robin, a marathoner living in Chicago, says they did there on account of snow. If the groundhog cannot get out of it's burrow it obviously cannot see its shadow, and therefore, winter should be ending soon. Shouldn't it? It only seems fair...
On the other hand, being snowed in makes for very good writing conditions.
Tip for the day (speaking from experience): do not look at google today. Whatever you do, especially you illustrators, do not look at google's art project, which they released on their website today. You might not get anything done for the rest of the month (year?).
At the very least, make sure you finish your picture book for the day before you go explore! You might find some inspiration for another picture book there.
